`IMPRSD'VEMEINT lIN RECIPROCATING- SAW-MILLS.

The'scheduile referred to in these'-ettera Patent and making part of the same.

I, EDWARDRHODES, of Philadelphia, count-y of Philadelphia, State of Pennsylvania, have `invented an Improvement in Reciprocating Saw-Mills, of which l the following isa specification. v

Nature mul Objwtofthe Invention. I My invention relates toimprovemcnts in gang-saws,

` l and in'the reciprocating slidiugframes by which the saws are usually carried; and

My invention consists in securing the saws to a sash or frame, soadapted to the main reciprocating frame, as fully described hereafter, that it can, with the gang of saws, he readily `removed from' the said main frame, to makeway for asimilar sash carrying a gang of perfect saws. l

` The" object of my invention is to avoidA the loss of j` Figure 2 a vertical section'of the saine; p

" p Y Geile-ral Description. 4

In carrying out my invention, I employ two frames,`

namely, `a maintiame arranged to slide in guides, and

u a` supplementary frame or sash, to which the saws are secured, and which is so tted to the main framet-hat it can bereadily detached therefrom.

The main frame is composed ot' two vertical barns,

11 H A and A', connected together by th'e upper crossehar l B and lower cross-har B.`

To this frameis fitted the sash, composed of the l verticalbars D ,and D', connected together by the cross-bars E and E. j

` The manner of fitting thesash to the frame will he Y j best observed on reference to g. 2,-whre it. will be j seen that the V-shaped projecting lower ends a a, of

the bars -D and D' of the sash,-are adapted to a V-` `'shaped bearing or groove in the upper edge of the lower cross-bar Bof the main frame, while projec 3 l .l ltions l) b, at the upper ends ofthe vertical bars ot the sash, fit into slotsin the upper cross-har B of the main frame. i v

The sash may he readily introduced into its place inthe main frame,by,irst holding it in the inclined l position shown in` 2, its V-shaped projections a l resting inthe simila1'ly-shaped groove in the cross-har l B' of the main frame, and then pushing theupper end frame caused vto reciprocate in guides.

secured ini'ts place by bolts ,or screws passed through holes f j', in the projections b b of the sash, and into and through'the cross-bar B of the main frame.

It will be unnecessary to explain how this sash may be readily detached from the main frame. I

A gang of saws, clzl, &c.,is secured to the sash in the same manner as they are usually secured to the ordiJ nary slidingframe.

The advantages of' my invent-ion may be described as follows: j Itis usual to connect a gang of saws to a single Hence, when one or more of the saws is damaged, (an accident which frequently occurs,) the movements of `the frame `inusthe stopped, the process ot' sawing must he discontinued, and the remaining whole saws of Y, the gang rendered inactive, until the damaged saws are removed and replaced by new ones, an operation demanding tedious manipulation. f

The delay caused by these accidents to saws secured in a gan g, directly to the reciprocatingframe, is'avoided by my plan of securing the saws to a frame or sash `detachable' from the'f'inaiu reciprocating frame, for, in

this case, should one or more of the ,saws be rendered u-nserviceable, the entire gang of saws, with the sash,

may 'he detached from themain frame, to be instantly replaced bya similar sash, containing a complete gang of' saws, which shouldbe always ou hand, so that no which yis at their disposal, could be devoted to leisurely repairing gangs of saws. y v

Claim.. Y The frame Bywth its groove, adapted for the r'eception ofthe lower edge of a detachable sawframe, E, having, at the upper end, projections b b, tting slots in thc said frame B, as specified.-

In testimonywhereof I have signed my name to.

this specilication in the presence ot' two subscribing witnesses. v
